Product Overview
The ABB 1SFB536068D1013 is a PST/PSTB Softstarter High Voltage Drive Board used within the high-power switching architecture of ABB PST and PSTB softstarter systems. It works with the softstarter control electronics and associated power circuitry to support the drive signals required for controlled motor operation.
In a complete PST/PSTB softstarter, the drive board sits within the interface between the electronic control section and the high-voltage power devices. Control commands generated by the softstarter are transferred through this circuitry to coordinate the switching operation of the power section during motor starting and stopping.
The board is suited to industrial motor-control equipment where controlled acceleration and stopping are required. Applications can include pumps, compressors, fans, conveyors, and process machinery using ABB softstarters to manage motor starting conditions.
During troubleshooting, the drive board should be considered together with the PST/PSTB control board, power semiconductors, internal connectors, protection circuitry, and motor circuit. A failure in any of these areas can affect the switching response of the complete softstarter.

Working Principle
The 1SFB536068D1013 operates as part of the drive path between the PST/PSTB control electronics and the high-voltage power-switching section. The control system determines the required operating sequence, while the drive circuitry delivers the corresponding switching signals to the power devices.
During motor starting, the drive board supports the controlled activation of the power-switching devices. This allows the PST/PSTB softstarter to regulate the electrical power applied to the motor instead of applying full line voltage immediately.
During a controlled stop, the same drive path supports the configured switching sequence used to reduce the motor’s operating speed or remove power according to the softstarter control strategy.
PST/PSTB Control Electronics → 1SFB536068D1013 → High-Voltage Power Devices → Motor
The drive board does not independently determine the complete softstarting sequence. Its operation depends on the control electronics, power section, protection circuitry, and correct internal connections.
Role in an ABB PST / PSTB Softstarter Control Architecture
The 1SFB536068D1013 belongs to the power-drive layer of the PST/PSTB softstarter. It links the control section with the high-voltage switching devices responsible for regulating the motor power circuit.

| System Element | Function |
|---|---|
| PLC / Controller | Provides automatic motor-control commands |
| Control Circuit | Transfers start, stop, and auxiliary commands |
| PST/PSTB Control Board | Processes softstarter operating logic |
| 1SFB536068D1013 | Provides drive signals for the power-control path |
| Power Switching Section | Controls electrical power delivered to the motor |
| Motor Protection | Monitors and protects the motor circuit |
| Motor | Converts electrical power into mechanical output |
| Driven Equipment | Performs the required industrial process |
The drive board therefore forms an intermediate stage between control processing and high-power switching rather than functioning as an independent controller.
Industrial Applications
| Application | Typical Use |
|---|---|
| Pump Systems | Controlled starting of industrial pump motors |
| Compressor Systems | Managing compressor motor acceleration |
| HVAC Equipment | Starting fans and blower motors with reduced stress |
| Conveyor Systems | Controlled acceleration of conveyor motors |
| Water Treatment | Starting pumps and process motors |
| Process Machinery | Motor control in automated production equipment |
| Material Handling | Starting heavy motor-driven machinery |
| Industrial Plants | High-power motor control within plant systems |
Installation and Maintenance
- Confirm that the 1SFB536068D1013 matches the installed PST/PSTB softstarter configuration.
- Isolate the softstarter from all electrical energy sources before opening the equipment.
- Follow the required discharge and high-voltage safety procedures before accessing internal circuitry.
- Document the original board connections and connector positions before removal.
- Use appropriate ESD precautions when handling the replacement drive board.
- Inspect connectors and board interfaces for contamination, loose connections, or physical damage.
- Check the associated power-switching components for signs of overheating or electrical damage.
- Install the replacement board in the correct position and ensure all connectors are fully seated.
- Verify internal wiring against the approved PST/PSTB electrical documentation.
- Restore control power and check softstarter status and diagnostic indications.
- Perform a controlled motor-start and stopping test while monitoring the softstarter response.
- Verify protection functions, external commands, and power-section operation before returning the equipment to service.

Technical FAQs
What does the 1SFB536068D1013 drive board do inside a PST/PSTB softstarter?
It forms part of the high-voltage drive path and transfers the required drive signals from the control section toward the associated power-switching devices.
How can a drive-board fault affect motor starting?
If the drive circuitry cannot deliver the required switching signals, the power section may not operate correctly even when the softstarter control electronics are receiving the start command. This can result in failed or abnormal motor starting.
What other components should be checked before replacing the drive board?
The PST/PSTB control board, internal connectors, power semiconductors, protection circuitry, and motor circuit should be inspected. Diagnostic information and the actual switching response should also be considered during fault isolation.
What commissioning checks are appropriate after drive-board replacement?
Verify all internal connections first, then check softstarter initialization, diagnostic status, control commands, protection functions, and power-section response. A controlled motor-start and stopping test should be completed before normal operation resumes.
